Hello to everybody and a big thank you for the job this forum is doing.
This is my first post so ... HELLO again.

Coming to my issue.
I ha a SD card 2Gb that normally I use in my infotainment CAR system.
Since last use, I can only read the files I have on it but I cannot anymore write or delete or format.
If I delete the files, everything seems correct but when I refresh files are still there.
If a write a file, it stays there and I can use it until I remove the SD. When I replug the file is not anymore visible.

If I use chkdsk it ends with disk error in writing the file allocation table.
